Abstract:
Bioactivity-guided fractionation of a methanolic extract of Buddleja officinalis led to the isolation of two monoterpenes, crocusatin M (1), crocusatin C (2), a flavonoid, acacetin (3), three lignans, lariciresinol (4), pinoresinol (5), and syringaresinol (6), and two triterpenoidal saponins, mimengoside B (7) and songarosaponin A (8). The structures of isolates were identified based on 1D-, 2D-NMR, and MS data analysis. All isolates were tested for their inhibition on LPS-induced NO production in RAW 264.7 cells. As a result, mimengoside B (7) and songarosaponin A (8) showed a mild inhibitory activity of NO production.
